摘要： The invention concerns a method to determine the composition of a fuel mixture from a first and at least a second fuel for the operation of an internal combustion engine with at least one combustion chamber, wherein the first and the second fuel have different boiling points and/or different enthalpies of evaporation. Provision is thereby made for the composition of the fuel mixture to be ascertained from the pressure in the combustion chamber and/or a parameter associated with the pressure and/or the time history of the pressure and/or the time history of a parameter associated with the pressure during and/or after an injection of fuel during a compression phase of the fuel-air mixture. An advantage of the method according to the invention is that when initially starting the engine after filling the tank (fueling), the fuel mixture ratio, which resulted from the filling of the tank (fueling), can already hereby be determined.

摘要： An internal combustion engine has at least one combustion chamber which may be closed by an intake valve, at least one air intake port which leads to the intake valve, and a fuel injection device which in association with the at least one combustion chamber has a first injector and a second injector for the metered injection of fuel into at least one intake port. To achieve significantly improved mixture preparation and combustion of the fuel-air mixture in the combustion chamber, the two injectors are configured such that the first injector injects a widely divergent spray cone having a large cone angle, and the second injector injects an only slightly divergent spray cone having a much smaller cone angle.

In at least one predefined operating state of the internal combustion engine, fuel is only injected by the at least one first injection valve into the induction manifold for a predetermined number of successive combustion cycles. In a subsequent combustion cycle, fuel is injected by the at least one first injection valve into the induction manifold and by the at least one second injection valve directly into the combustion chamber or only by the at least one second injection valve directly into the combustion chamber.

摘要： A method and a device for operating an internal combustion engine and an internal combustion engine are described, the fuel being injectable directly into a combustion chamber in particular via at least one first injector and also being injectable into an intake manifold in particular via at least one second injector. For injection of fuel in a full-load operating state of the internal combustion engine, a first selection is made from the at least one first injector and the at least one second injector having a first metering range, including a full-load injection quantity required for the full-load operating state. For injection of fuel in a partial-load operating state of the internal combustion engine, a second selection is made from the at least one first injector and the at least one second injector having a second metering range, including the adjustment of a minimum fuel injection quantity required for operating the internal combustion engine. The first selection and the second selection are made differently, in such a way that only the metering range of the first selection includes the full-load injection quantity and/or that only the metering range of the second selection covers the minimum fuel injection quantity required for operating the internal combustion engine.

摘要： In a method for operating an internal combustion engine, a setpoint fuel quantity to be injected is subdivided into a first fuel quantity which is to be injected into an intake manifold of the internal combustion engine, and a second fuel quantity to be injected directly into a combustion chamber of the internal combustion engine. The subdivision of the fuel quantity is performed as a function of a temperature that is characteristic for the operation of the internal combustion engine, e.g., in a start of the internal combustion engine, and the ratio between the first fuel quantity and the second fuel quantity is continually modified as a function of the temperature.
